SPECIFICATION forming part of Letters Patent No. 371,932, dated-October25, 1887.

Application tiled December 27,

.To @ZZ whom, it may concern:

Be it known that I, CHARLns H. H. FRENCH, a citizen of the UnitedStates, residing at Hollister, in the county of San Benito and State ofCalifornia, have invented certain new and useful ImprovementsinHay-Presses, of which the following is a description.

My invention relates to hay-presses, and the purpose thereof is toincrease the power of the press mechanism and to render the same assimple and easy of operation as possible. It is also my purpose tosimplify and improve the construction of the press-box, and to promotethe ease with which the hay is inserted and removed.

The invention consists in the several novel 4features of constructionand new combinations of parts hereinafter fully set forth and detinitelypointed'out in the claims which follow this specification.

In the drawings accompanying this application, Figure l is a view of thepress laid upon` its side, and Fig. 2 is ahorizontal section of Fig. lon the line X X.

The reference-letter a denotes the cover or lid of the press-box, whichis hinged to the box proper, c', by means of a plate, c2, which engageswith eyes or staples fr driven into the sides a". From the point atwhich this hinge is located the side pieces rise as they extend towardthe frontend of the press, until at the point b they are some distanceabove the top of the box. Upon these side pieces, a", is mounted alever, c, turning in staples e', a crank, c2, forming part of said leverand engaging with akeeper or loop, c3, .on the cover a. By swinging thelever c the cover may be raised and lowered, as shown in Fig. 2.

The letter d denotes a pair of inclined plates resting at one end uponthe floor or other support and supported at the other end by averticalU-shaped frame, c, to which the plates d are attached by rivets d2. Thepress-boX a is arranged within the frame@ and between the plates d, itsforward end being supported upon a pivot-shaft, d', passing through theends of the plates d.

Vithin the press-box is arranged the pluir ger c2, having an eye, c3, inits rear end, to which is connected an arm, e, swinging from a shaft, f,in the elevated' ends of the plates d.

Connected to the eye c3 is a pitman,f, the other end of which isattached to the short arm i of a bell-crank lever, i', said lever havingits fnlcrum upon a shaft, g, journaled in extensions d of the plates d.Vhen the plun ger e2 is retracted, as shown in Fig. 2, the press-box isswung upon the pivot d until its bottom approaches the central orconnecting portion of the frame c. The cover may then be opened and thematerial to be pressed placed in the box a. The cover being then closedthe lever z" is swung toward the rear, raising the end of the press-boxand driving the plunger forward. As the movement continues the arm ccomes into or nearly into a straight line with the plunger, while theshort arm i of the bell-crank approaches a right angle to the line inwhich the power is applied through the plunger, as shown by dotted linesVin Fig. 2. It will be seen that under this arrangement the plunger czand the arm e4 practically constitute an elbow -joint or togglelever,and that as the arm z' of the bell-crank lever t" approaches its limitof movement its power rapidly increases, the toggle action of theplunger and arm e having its greatest power at t-he same time.

The press normally stands upon the U- shaped frame-piece e, the lid abeing upon top; but for purposes of illustration it is shown in thefigures of the drawing as laid upon its side.

What I claim isl. In a hay-press, the combination, with a press-boxpivotally mounted at or near one end and a frame supporting the same, ofa plunger movable in said box, au arm journaled at one end in thesupportingsframe and jointed at the other end to the plunger, and alever mounted above the said parts and connected by an arm and pitmantothe plunger whereby thclatter maybe raised and lowered, substan tiallyas specified.

2. In a hay-press, the combination, with a pivotallymounted pressbox,and a plunger movable therein, of an arm mounted en a rigid support inrear of said box and plunger and pivoted to the latter, and a bell-crankthe end of the plunger and having its short arm connected by a pitmanwith the plunger, substantially as specified.

lever journaled in said rigid support" above,

Ico

3. The combination with the upright and inclined frames e and d, of apress-box pivot.- ally mountedat one end on the latter frame and havinga hinged cover or lid, a, a lever,

5 c, journaled on the raised sides b of the box and having a crank, 02,and a loop or keeper, c3, with which the said crank engages,Substantially as specified.

' 4. The combination, with the press-box a',

1o and the supporting-frames d and e, between l which it is pivotallysupported near one end, of the plunger e2, the 2mn e, jointed to it, thepitman f', connected to the said parts at the point Where they arejointed, and the bellcrank lever i', to the short arm of which' the 15pitman is connected, substantially as specified.
